"In the spring of the year after was born in Gondolin Eärendil Halfelven, the son of Tuor and Idril Celebrindal; and that was five hundred years and three since the coming of the Noldor to Middle-earth. Of surpassing beauty was Eärendil, for a light was in his face as the light of heaven, and he had the beauty and the wisdom of the Eldar and the strength and hardihood of the Men of old; and the Sea spoke ever in his ear and heart, even as with Tuor his father."
